1. Half load at +Vout and half load at -Vout

2. Up to 70% of the total power or current can be drawn from either

of the two outputs.

3. Time for output voltage to settle within 1% of steady-state value

4. Verified by initial electrical design verification. Post design

verification, parameter shall be guaranteed to the limits specified

5. End-of-Life performance includes aging and radiation

degradation and is within standard limits except where noted

6. 5% Load to Full Load at -55°C.
